More Materials

TENCEL™ Lyocell

TENCEL™ Lyocell

Created from the wood pulp of responsibly forested trees, TENCEL lyocell is a healthy, natural fabric that we have engineered to be supremely soft.

We use lyocell as a carrier for most of our textile products, as its production is certified, environmentally sustainable, and less wasteful than conventional cotton or synthetics. Treating it with our custom textile finishing technology enhances the natural softness, imparting a luxurious feel and sheen with a silk-like slip. Breathable, hypoallergenic, cool to the touch, anti-static, OEKO-TEX certified and skin and hair-friendly. It's practically perfect for our purposes.

Mica Nylon

Mica Nylon

The Mica fiber has unique heat-conducting properties, making it the perfect material to utilize for fabric surfaces. It allows us to maximize the efficacy of our textiles: Heat when you need it.

It's not simple nylon, but a mineral-infused fiber with a natural structure of thin sheets that maximizes the performance of our products. Mica facilitates heat transfer from skin to CLIMA fiber with a conduction rate 5X higher than conventional polyester/microfiber materials. Utilized in our shell surface fabric blend it is cool to the touch, moisture-absorbing, anti-static, and the high surface area gives it a deodorizing effect similar to active carbon. Keeps you cool when you're comfortable.

Talalay Latex

Talalay Latex

When constructing the perfect pillow with temperature-regulating capabilities, we landed on Talay latex. It’s naturally breathable and resists heat. Never flat, but flat-out bouncy.

We deploy it as a core within our pillows, adding bounce to them – a certain amount of give. This ensures your pillow never falls flat and feels as soft as it is supportive. Talalay is lightweight and naturally cool, making it the perfect addition to our CLIMA collection. Among its benefits are its hypoallergenic nature, antifungal properties, and in some cases, antibacterial properties. Like all Sijo textile products, it is OEKO-TEX certified. Its production is environmentally sustainable, making all sides of this pillow pleasantly cool.

Recycled Polyester

Recycled Polyester

Planet Safe: our recycled polyester is made from upcycled water bottles. Recycling and treating the material uses less water and allows us to enhance its properties for a finely constructed fluff.

As the basic building block to your bedding system, the comforter needs to be comfortable, above all. To achieve the right amount of puffiness, with sustainability as another key metric, we decided to recycle polyester. All of our fiber material is sourced from GRS-certified facilities. Food-grade plastic containers are transformed — from accumulating in landfills into ideal bedding materials and textile products. Naturally soft, earth-friendly, and OEKO-TEX certified like all of our products. Low impact, highly comfortable.

Sleep meets
performance.

The CLIMA collection was crafted using the CLIMA fiber, our most advanced fabric ever. Exclusive to Sijo, we designed our textiles with proprietary technology to keep you at your perfect temperature throughout the night, storing heat when you’re warm, and releasing it back when you get cool. This collection converges technological advancement and aesthetics, beyond the capabilities or comfort of anything synthetic. Nature, enhanced by engineering.

/F.A.Q /

The CLIMA fiber is a Phase Change Material (PCM) that can absorb and release heat due to the patented manufacturing process of the fabric and fibers. This keeps your body at the optimal temperature for sleep, which is between 82 and 89° F, because the bedding is able to trap in and store heat to keep you cool, and can disperse that heat back toward the body should you need a bit more warmth.

This is great for hot, warm and cold sleepers as the fabric and fill for this collection are thermal regulating, which will keep you at the optimal skin temperature for high quality sleep.

We offer a comforter, pillows, mattress pad, sheets, duvet covers and pillow cases in this collection. The CLIMA fabric and fillings are breathable and temperature regulating, and work beautifully as a system to maximize your comfort as you sleep.

Yes, our comforter and pillows are sized to pair with our pillow cases and duvet covers from our Eucalyptus and French Linen bedding collections.

Like all of our textiles and bedding products, this collection has Oeko-Tex 100 Certification, meaning it is free from harsh and harmful chemicals and dyes. 

Our new collection also has an FSC certificate. This ensures that the wood pulp used to create the CLIMA products are sourced from responsibly managed forests. 

Finally, the recycled material elements of our products are Global Recycling Standard (GRS) certified.
